LOUIS ALLEN, OF SALEM, MASSACHUSETTS.

BRIDGE-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 770,036, dated September 13, 1904.

1 Application filed January 2'7, 1904. Serial No. 190,853- (No model.)

, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to signals for Warning men on top of railroad-trains of the near approach of the train to a bridge; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side View of the signal. Fig. 2 is a side view of one'of the slats and its attachments, drawn to a larger scale. Fig. 3 is an end view of the said parts shown in Fig. 2.

A is a post secured in the ground at the side of a railroad-track and provided with a bracket (4 at its top.

B is a frame provided with two upwardlyprojecting arms 6 and b and pivoted to the bracket a by means of a pin (J.

D is a cord or other suitable connection for securing .the said frame to the post and holding the signal in its raised position, as shown in the drawings.

E is the signal-arm, which is formed of a pipe or tube inserted in a hole in the frame and provided with collars e to prevent it from sliding.

F is an extension-arm which slides inside the main arm E and which may also be a tube, if desired.

Braces g g are provided and are secured to collars on the main arm at one end and to the rear arm 5 at the other end. The arm 5 supports the intermediate parts of the said braces and prevents them from sagging.

Gr is a cross-bar which is suspended from the main arm E or from its extension by means of supports it, which are preferably jointed and which may be formed of rods, chains, or any other suitable devices. The cross-bar G is preferably trough-shaped in cross-section and is arranged in an inverted position.

I represents wooden slats or sticks which have sockets i secured to their top ends.

J represents rings secured to the cross-bar G, and j represents loops which engage with the said rings. Thelower end portions of the said loops are passed through holes is inthe said sockets and are bent around to form hooks so that the slats or sticks are supported from the said cross-bar.

The slats or sticks are arranged in a row along the cross-bar, and they take the place of the ropes which are usually provided on signals of this sort. The slats or sticks are easily broken when struck by any moving object, and the arm E is then lowered on its pivot, so that it hangs vertical. When in this position, the slats or sticks can be reached from the ground and can be replaced when necessary.

hat I claim is 1. In a bridge-signal, the combination, with a supporting-post, of a signal-arm pivoted to the said post, means for holding the said arm in its raised position, a cross-bar suspended from the said arm, and a row of slats or sticks suspended from the said cross-bar.

2'. In a bridge-signal, the combination, with a supporting-post, of a bracket pivoted to the said post, a tubular signal-arm inserted in a hole in the said bracket and provided with stops to prevent it from sliding, braces supporting the outer end of the said arm from the said'bracket, and a row of signal-pieces suspended from the said arm.

3. In a bridge-signal, the combination, with a supporting-arm, of a cross-bar suspended from the .said arm, rings attached to the said cross-bar, a row of slats or sticks having sockets at their upper ends, and loops which engage with the said rings and have their lower portions passed through holes in the said sockets and bent to form hooks which support said sockets.

In testimony whereof I affix my signature in presence of two witnesses.

LOUIS ALLEN.
